Tunable Sound Absorption via Evanescent‐Wave Coupling in Asymmetric Bilayer Metasurfaces

open access: yesAdvanced Science, EarlyView.
Tunable sound absorption is realized through a bilayer metasurface system governed by evanescent‐wave coupling. This work demonstrates that such evanescent‐wave coupling provides a controllable scattering channel that destructively interferes with the specular reflection.

Innovative Metasurface Colorimetric Cell‐on‐a‐Chip Sensor for Continuous, Label‐Free, Non‐Destructive Assessment of Intestinal Barrier Dynamics

open access: yesAdvanced Science, EarlyView.
We developed a real‐time, label‐free, high‐throughput cell‐on‐a‐chip system based on a metasurface plasmon resonance colorimetric sensor (MetaSPRCS) to evaluate intestinal barrier function. This platform enables continuous monitoring of cell adhesion, proliferation, and barrier layer formation, disruption, and repair.

On‐Chip Silicon‐Based Micro‐Reflector Pixelated with Micro‐Light‐Emitting Diodes for Augmented Reality Projection Displays

open access: yesAdvanced Science, EarlyView.
This paper presents a pixel‐by‐pixel on‐chip silicon‐based micro‐reflector device (SMRD) for µLEDs that enables simultaneous light‐extraction enhancement and directional emission control. The scalable architecture significantly improves forward light utilization and suppresses pixel crosstalk.

High‐Brightness, Wide‐Gamut, and High‐Resolution Structural Colors via Ultrafast Laser Oxidation of Ti/TiO2 Films

open access: yesAdvanced Science, EarlyView.
Ultrafast laser writing on titanium (Ti)–titanium dioxide (TiO2)–Ti sandwich films triggers controllable oxidation (〉200 nm) to create vivid, durable structural colors. The colors reach 〉 80% of the standard RGB (sRGB) gamut, up to 60% peak reflectance, and 30,000 dots per inch (DPI) resolution for art and anti‐counterfeiting.
